1. Summary of Significant Accounting Policies | 12 Months Ended | ||||||||||||
Dec. 31, 2014 | |||||||||||||
Accounting Policies [Abstract] | |||||||||||||
Summary of Significant Accounting Policies | Atrion Corporation and its subsidiaries (“we,” “our,” “us,” “Atrion” or the “Company”) develop and manufacture products primarily for medical applications. We market our products throughout the United States and internationally. Our customers include hospitals, distributors, and other manufacturers. Atrion Corporation’s principal subsidiaries through which these operations are conducted are Atrion Medical Products, Inc., Halkey-Roberts Corporation and Quest Medical, Inc. | ||||||||||||
Principles of Consolidation | |||||||||||||
The consolidated financial statements include the accounts of Atrion Corporation and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. | |||||||||||||
Estimates | |||||||||||||
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amount of revenues and expenses during the reporting periods. Actual results could differ from those estimates. | |||||||||||||
Cash and Cash Equivalents and Investments | |||||||||||||
Cash equivalents include cash on hand and in the bank as well as money market accounts and debt securities with maturities at the time of purchase of 90 days or less. | |||||||||||||
Our investments consist of taxable corporate and United States government agency bonds and equity securities. We classify our investment securities in one of three categories: held-to-maturity, trading, or available-for-sale. Securities that we have the positive intent and ability to hold to maturity are reported at amortized cost and classified as held-to-maturity securities. If we do not have the intent and ability to hold a security to maturity, we report the investment as available-for-sale securities. We report available-for-sale securities at fair value with unrealized gains and, to the extent deemed temporary, unrealized losses recorded in stockholders’ equity as accumulated other comprehensive loss. We consider investments which will mature in the next 12 months as current assets. The remaining investments are considered non-current assets including our investment in equity securities which we intend to hold longer than 12 months. We periodically evaluate our investments for impairment. We do not believe any unrealized losses represent other-than-temporary impairments based on our evaluation of available evidence as of December 31, 2014. | |||||||||||||
The components of the Company’s cash and cash equivalents and our short and long-term investments as of December 31, 2014 and 2013 are as follows (in thousands): | |||||||||||||

Trade Receivables | |||||||||||||
Trade accounts receivable are recorded at the original sales price to the customer. We maintain an allowance for doubtful accounts to reflect estimated losses resulting from the failure of customers to make required payments. On an ongoing basis, the collectability of accounts receivable is assessed based upon historical collection trends, current economic factors and the assessment of the collectability of specific accounts. We evaluate the collectability of specific accounts and determine when to grant credit to our customers using a combination of factors, including the age of the outstanding balances, evaluation of customers’ current and past financial condition, recent payment history, current economic environment, and discussions with appropriate Company personnel and with the customers directly. Accounts are written off when we determine the receivable will not be collected. | |||||||||||||
Inventories | |||||||||||||
Inventories are stated at the lower of cost (including materials, direct labor and applicable overhead) or market. Cost is determined by using the first-in, first-out method. The following table details the major components of inventory (in thousands): | |||||||||||||

Finished goods | 9,847 | 9,276 | |||||||||||
Total inventories | $ | 28,022 | $ | 26,266 | |||||||||
Accounts Payable | |||||||||||||
We reflect disbursements as trade accounts payable until such time as payments are presented to our bank for payment. At December 31, 2014 and 2013, disbursements totaling approximately $613,000 and $443,000, respectively, had not been presented for payment to our bank. | |||||||||||||
Income Taxes | |||||||||||||
We account for income taxes utilizing Accounting Standards Codification (ASC) 740, Income Taxes , or ASC 740. ASC 740 requires the asset and liability method for the recording of deferred income taxes, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statement and the tax bases of assets and liabilities, as measured at current enacted tax rates. When appropriate, we evaluate the need for a valuation allowance to reduce deferred tax assets. | |||||||||||||
ASC 740 also requires the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attributes of income tax positions taken or expected to be taken on a tax return. Under ASC 740, the impact of an uncertain tax position taken or expected to be taken on an income tax return must be recognized in the financial statements at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more-likely-than-not of being sustained. | |||||||||||||
Our uncertain tax positions are recorded as “Other non-current liabilities.” We classify interest expense on underpayments of income taxes and accrued penalties related to unrecognized tax benefits in the income tax provision. | |||||||||||||
Property, Plant and Equipment | |||||||||||||
Property, plant and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Additions and improvements are capitalized, including all material, labor and engineering costs to design, install or improve the asset. Expenditures for repairs and maintenance are charged to expense as incurred. The following table represents a summary of property, plant and equipment at original cost (in thousands): | |||||||||||||

Total property, plant and equipment | $ | 142,171 | $ | 130,504 | |||||||||
Depreciation expense of $8,454,000, $8,413,000 and $7,448,000 was recorded for the years ended December 31, 2014, 2013 and 2012, respectively. Depreciation expense is recorded in either cost of goods sold or operating expenses based on the associated assets’ usage. | |||||||||||||
Patents and Licenses | |||||||||||||
Costs for patents and licenses acquired are determined at acquisition date. Patents and licenses are amortized over the useful lives of the individual patents and licenses, which are from 7 to 20 years. Patents and licenses are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. | |||||||||||||
Goodwill | |||||||||||||
Goodwill represents the excess of cost over the fair value of tangible and identifiable intangible net assets acquired. Annual impairment testing for goodwill is done using a qualitative assessment on goodwill impairment to determine whether it is necessary to perform the two-step goodwill impairment test. Goodwill is also reviewed whenever events or changes in circumstances indicate a change in value may have occurred. We have identified three reporting units where goodwill was recorded for purposes of testing goodwill impairment annually: (1) Atrion Medical Products, Inc., (2) Halkey-Roberts Corporation and (3) Quest Medical, Inc. The total carrying amount of goodwill in each of the years ended December 31, 2014, 2013 and 2012 was $9,730,000. Our evaluation of goodwill during each year resulted in no impairment losses. | |||||||||||||
Current Accrued Liabilities | |||||||||||||
The items comprising current accrued liabilities are as follows (in thousands): | |||||||||||||

Total accrued liabilities | $ | 4,950 | $ | 4,423 | |||||||||
Revenues | |||||||||||||
We recognize revenue when our products are shipped to our customers, provided an arrangement exists, the fee is fixed and determinable and collectability is reasonably assured. All risks and rewards of ownership pass to the customer upon shipment. Net sales represent gross sales invoiced to customers, less certain related charges, including discounts, returns and other allowances. Revenues are recorded exclusive of sales and similar taxes. Returns, discounts and other allowances have been insignificant historically. | |||||||||||||
Shipping and Handling Policy | |||||||||||||
Shipping and handling fees charged to customers are reported as revenue and all shipping and handling costs incurred related to products sold are reported as cost of goods sold. | |||||||||||||
Research and Development Costs | |||||||||||||
Research and development costs relating to the development of new products and improvements of existing products are expensed as incurred. | |||||||||||||
Stock-Based Compensation | |||||||||||||
We have stock-based compensation plans covering certain of our officers, directors and key employees. As explained in detail in Note 8, we account for stock-based compensation utilizing the fair value recognition provisions of ASC 718, Compensation-Stock Compensation, or ASC 718. | |||||||||||||
New Accounting Pronouncements | |||||||||||||
From time to time, new accounting pronouncements applicable to us are issued by the Financial Accounting Standards Board, or FASB, or other standards setting bodies, which we will adopt as of the specified effective date. Unless otherwise discussed, we believe the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial statements upon adoption. | |||||||||||||
Fair Value Measurements | |||||||||||||
Accounting standards use a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers are: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists therefore requiring an entity to develop its own assumptions. | |||||||||||||
As of December 31, 2014 and 2013, we held certain investments in corporate and government debt securities as well as certain equity securities. These investments are all considered Level 2 assets and the fair value of our investments were estimated using recently executed transactions and market price quotations (see Note 2). | |||||||||||||
The carrying values of our other financial instruments including cash and cash equivalents, money market accounts, accounts receivable, accounts payable, accrued liabilities, and accrued income and other taxes approximated fair value due to their liquid and short-term nature. | |||||||||||||
Concentration of Credit Risk | |||||||||||||
Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. | |||||||||||||
Our cash and cash equivalents are held in accounts with financial institutions that we believe are creditworthy. Certain of these amounts at times may exceed federally-insured limits. At December 31, 2014, approximately 91% of our cash and cash equivalents were uninsured. We have not experienced any credit losses in such accounts and do not believe we are exposed to any significant credit risk on these funds. | |||||||||||||
We have investments in United States government agency securities and corporate bonds. As a result, we are exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer and otherwise. Approximately 24% of our aggregate fixed-income investments are below investment grade. These securities have a higher degree of credit or default risk and a greater exposure to credit risk and may be less liquid in times of economic weakness or market disruptions. | |||||||||||||
For accounts receivable, we perform ongoing credit evaluations of our customers’ financial condition and generally do not require collateral. We maintain reserves for possible credit losses. As of December 31, 2014 and 2013, we had allowances for doubtful accounts of approximately $22,000 and $86,000, respectively. The carrying amount of the receivables approximates their fair value. Our customer that generates our largest revenues accounted for 6.5%, 8.2% and 16.3% of accounts receivable as of December 31, 2014, 2013 and 2012, respectively. No other customer exceeded 10% of our accounts receivable as of December 31, 2014, 2013 or 2012. | |||||||||||||

Investments | As of December 31, 2014 and 2013, we held certain investments that were required to be measured for disclosure purposes at fair value on a recurring basis. These investments were considered Level 2 investments. We consider as current assets those investments which will mature in the next 12 months. The remaining investments are considered non-current assets including our investment in equity securities which we intend to hold longer than 12 months. | ||||||||||||||||

Debt Disclosure [Abstract] | |
Line of Credit | We have a $40.0 million revolving credit facility with a money center bank pursuant to which the lender is obligated to make advances until October 1, 2016. The credit facility is secured by substantially all our inventories, equipment and accounts receivable. Interest under the credit facility is assessed at 30-day, 60-day or 90-day LIBOR, as selected by us, plus one percent (1.16 percent at December 31, 2014) and is payable monthly. We had no outstanding borrowings under the credit facility at December 31, 2014 or 2013. At any time during the term, we may convert any or all outstanding amounts under the credit facility to a term loan with a maturity of two years. Our ability to borrow funds under the credit facility from time to time is contingent on meeting certain covenants in the loan agreement, the most restrictive of which is the ratio of total debt to earnings before interest, income tax, depreciation and amortization. At December 31, 2014, we were in compliance with all of those covenants. |

We are subject to United States federal income tax as well as to income tax of multiple state jurisdictions. We have concluded all United States federal income tax matters for years through 2010. In January 2009, the Internal Revenue Service, or IRS, began examining certain of our United States federal income tax returns for 2006, 2007 and 2008. This audit was favorably concluded in the third quarter of 2012 when the IRS appeals group allowed 100% of the tax credits claimed for our R&D expenditures during those years. Our unrecognized tax benefits were reduced at that time on the basis of this favorable settlement in the amount of approximately $641,000. All material state and local income tax matters have been concluded for years through 2010. | ||||||||||||||
We recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense. The liability for unrecognized tax benefits included accrued interest of $9,000, $21,000 and $26,000 at December 31, 2014, 2013 and 2012, respectively. Tax expense for the year ended December 31, 2014, 2013 and 2012 included a net interest benefit of $12,000, $5,400 and $51,000, respectively. | ||||||||||||||

Equity [Abstract] | |
Stockholders' Equity | Our Board of Directors has at various times authorized repurchases of our stock in open-market or privately-negotiated transactions at such times and at such prices as management may from time to time determine. On August 16, 2011, our Board of Directors adopted a new stock repurchase program pursuant to which we can repurchase up to 200,000 shares of our common stock from time to time in open market or privately-negotiated transactions. This stock repurchase program has no expiration date but may be terminated by the Board of Directors at any time. As of December 31, 2014, 54,026 shares remained available for repurchase under this program. We repurchased 74,746, 36,666 and 26,562 shares under the program during 2014, 2013 and 2012, respectively. |
We have increased our quarterly cash dividend payments in September of each of the past three years. The quarterly dividend was increased to $.56 per share in September 2012, to $.64 per share in September 2013 and to $.75 per share in September 2014. On December 10, 2012 we also paid a special cash dividend to stockholders of $10.00 per share. Holders of stock units earned non-cash dividends of $33,000 in 2014, $29,000 in 2013 and $157,000 in 2012. | |
We have a Rights Plan which is intended to protect the interests of stockholders in the event of a hostile attempt to take over the Company. The rights, which are not presently exercisable and do not have any voting powers, represent the right of our stockholders to purchase at a substantial discount, upon the occurrence of certain events, shares of our common stock or of an acquiring company involved in a business combination with us. This plan, which was adopted in August 2006, expires in August 2016. | |

Compensation Related Costs [Abstract] | |||||||||||||||||
Stock Plans | At December 31, 2014, we had three stock-based compensation plans which are described more fully below. We account for our plans under ASC 718, and the disclosures that follow are based on applying ASC 718. ASC 718 requires that cash flows from the use of stock-based compensation resulting from tax benefits in excess of recognized compensation cost (excess tax benefits) be classified as financing cash flows. We recorded $168,000, $15,000 and $1,412,000 of such excess tax benefits as financing cash flows in 2014, 2013 and 2012, respectively. | ||||||||||||||||
Our Amended and Restated 2006 Equity Incentive Plan, or 2006 Plan, provides for awards to key employees, non-employee directors and consultants of incentive and nonqualified stock options, restricted stock, restricted stock units, deferred stock units, stock appreciation rights, performance shares and other stock-based awards. Under the 2006 Plan, 200,000 shares, in the aggregate, of common stock have been reserved for awards. The purchase price of shares issued on the exercise of options must be at least equal to the fair market value of such shares on the date of grant. The options granted become exercisable and expire as determined by the Compensation Committee. As of December 31, 2014, there remained 52,751 shares for future stock-based awards under the 2006 Plan. | |||||||||||||||||
In May 2007, we adopted our Deferred Compensation Plan for Non-Employee Directors (as amended, the “Deferred Compensation Plan”), and 2,500 shares of our common stock were initially reserved for issuance thereunder. This plan allows our non-employee directors to elect to receive stock units in lieu of all or part of the cash fees they are receiving for their services as directors. On the first business day of each calendar year, each participating non-employee director is credited with a number of stock units determined on the basis of the foregone cash fees and the closing price of our common stock on the next preceding date on which shares of our stock were traded. The stock units are converted to shares of our common stock on a one-for-one basis at a future date as elected in advance by the director, but no later than the January following the year in which the director ceases to serve on the Board of Directors, and the shares are delivered to the director. As of December 31, 2014, there remained 1,599 shares of common stock reserved for issuance upon the conversion of stock units which may be credited in the future to non-employee directors. | |||||||||||||||||
In May 2007, we also adopted our Non-Employee Director Stock Purchase Plan, (as amended, the “Director Stock Purchase Plan”), and 2,500 shares of our common stock were initially reserved for issuance thereunder. Under this plan, our non-employee directors may elect to receive on the first business day of the calendar year fully-vested stock and restricted stock in lieu of some or all of their fees payable to them during such year. The foregone fees are converted into shares of fully-vested stock and restricted stock on the first business day of such calendar year based on the closing price of our common stock on the next preceding date on which shares of our stock were traded. The restricted stock vests in equal amounts on the first day of the next three succeeding calendar quarters provided the non-employee director is then serving on our Board of Directors. As of December 31, 2014, there remained 1,126 shares reserved for issuance under such plan. | |||||||||||||||||
A summary of stock option transactions for the year ended December 31, 2014 is presented below: | |||||||||||||||||

All nonvested options outstanding at December 31, 2014 are expected to vest. We estimate the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. None of our grants includes performance-based or market-based vesting conditions. The expected life represents the period that our stock-based awards are expected to be outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The fair value of stock-based payments, funded with options, is valued using the Black-Scholes valuation method with a volatility factor based on our historical stock trading history. We base the risk-free interest rate using the Black-Scholes valuation method on the implied yield currently available on U.S. Treasury securities with an equivalent term. We base the dividend yield used in the Black-Scholes valuation method on our dividend history. | |||||||||||||||||
There were no options granted in 2014 or 2013. The fair value for the options granted in 2012 was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions: | |||||||||||||||||

The weighted average grant date fair value of the options granted in 2012 was $40.38. The total intrinsic value of options exercised during 2012 was $3.1 million. There were no options exercised in 2014 and 2013. The total intrinsic values of options outstanding and options currently exercisable at December 31, 2014, were $6.8 million and $3.5 million, respectively. | |||||||||||||||||
During 2014, 1,400 shares of restricted stock were awarded under the 2006 Plan. Under the terms of our restricted stock awards, the restrictions usually lapse over a five-year period, but the 2014 grant was vested over a four-month period ended September 30, 2014. During the vesting period, holders of restricted stock have voting rights and earn dividends, but the shares may not be sold, assigned, transferred, pledged or otherwise encumbered. Nonvested shares are generally forfeited on termination of employment unless otherwise provided in the participant’s employment agreement or the termination is in connection with a change in control. A summary of changes in nonvested restricted stock for the year ended December 31, 2014 is presented below: | |||||||||||||||||

During 2014, restricted stock units were awarded to certain employees under the 2006 Plan. All of our restricted stock units are convertible to shares of stock on a one-for-one basis when the restrictions lapse, which is generally after a five-year period. Nonvested stock units are generally forfeited on termination of employment unless the termination is in connection with a change in control. During the vesting period, holders of all restricted stock units earn dividends in the form of additional units. During 2014, one non-employee director elected to receive stock units in lieu of a portion of his cash fees for his services as a member of the Board of Directors. | |||||||||||||||||

All nonvested restricted stock units at December 31, 2014 are expected to vest. The total intrinsic value of all outstanding stock units which were not convertible at December 31, 2014, including 417 stock units held for the accounts of non-employee directors, was $5,194,000. The total intrinsic value of restricted stock units that vested and were converted during 2014 was $283,000. The total fair value of directors’ stock units that vested and were converted was $8,000 during each of 2014 and 2013, and $22,000 during 2012. | |||||||||||||||||
Stock awards that vested immediately were awarded under the 2006 Plan to non-employee directors totaling $240,000 in value in 2014 and $120,000 in each of 2013 and 2012. Compensation related to stock awards, restricted stock and stock units is based on the fair market value of the stock on the date of the grant. These fair values are then amortized on a straight-line basis over the requisite service periods of the entire awards, which is generally the vesting period. Compensation related to stock options is based on the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. For the years ended December 31, 2014, 2013 and 2012, we recorded stock-based compensation expense as a G&A expense in the amount of $2,209,000, $1,586,000 and $1,482,000, respectively, for all of the above mentioned stock-based compensation arrangements. The total tax benefit recognized in the income statement from stock-based compensation arrangements for the years ended December 31, 2014, 2013 and 2012, was $773,000, $555,000 and $516,000, respectively. | |||||||||||||||||

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | From time to time and in the ordinary course of business, we may be subject to various claims, charges and litigation. In some cases, the claimants may seek damages, as well as other relief, which, if granted, could require significant expenditures. We accrue the estimated costs of settlement or damages when a loss is deemed probable and such costs are estimable, and accrue for legal costs associated with a loss contingency when a loss is probable and such amounts are estimable. Otherwise, these costs are expensed as incurred. If the estimate of a probable loss or defense costs is a range and no amount within the range is more likely, we accrue the minimum amount of the range. As of December 31, 2014, the Company had no ongoing litigation or arbitration for such matters. |
We had a dispute which was favorably settled in the third quarter of 2007. This settlement was amended in December 2008. The amended settlement agreement provides that we may receive annual payments from 2009 through 2024. We have not recorded $5.0 million in potential future payments under this settlement as of December 31, 2014 due to the uncertainty of payment. | |
We have arrangements with three of our executive officers pursuant to which the termination of their employment under certain circumstances would result in lump sum payments to them. Termination under such circumstances at December 31, 2014 could have resulted in payments aggregating $6.0 million. |

1. Summary of Significant Accounting Policies (Policies) | 12 Months Ended | ||||||||||||
Dec. 31, 2014 | |||||||||||||
Accounting Policies [Abstract] | |||||||||||||
Principles of Consolidation | The consolidated financial statements include the accounts of Atrion Corporation and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. | ||||||||||||
Estimates | The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amount of revenues and expenses during the reporting periods. Actual results could differ from those estimates. | ||||||||||||
Cash and Cash Equivalents | Cash equivalents include cash on hand and in the bank as well as money market accounts and debt securities with maturities at the time of purchase of 90 days or less. | ||||||||||||
Our investments consist of taxable corporate and United States government agency bonds and equity securities. We classify our investment securities in one of three categories: held-to-maturity, trading, or available-for-sale. Securities that we have the positive intent and ability to hold to maturity are reported at amortized cost and classified as held-to-maturity securities. If we do not have the intent and ability to hold a security to maturity, we report the investment as available-for-sale securities. We report available-for-sale securities at fair value with unrealized gains and, to the extent deemed temporary, unrealized losses recorded in stockholders’ equity as accumulated other comprehensive loss. We consider investments which will mature in the next 12 months as current assets. The remaining investments are considered non-current assets including our investment in equity securities which we intend to hold longer than 12 months. We periodically evaluate our investments for impairment. We do not believe any unrealized losses represent other-than-temporary impairments based on our evaluation of available evidence as of December 31, 2014. | |||||||||||||
The components of the Company’s cash and cash equivalents and our short and long-term investments as of December 31, 2014 and 2013 are as follows (in thousands): | |||||||||||||

Trade Receivables | Trade accounts receivable are recorded at the original sales price to the customer. We maintain an allowance for doubtful accounts to reflect estimated losses resulting from the failure of customers to make required payments. On an ongoing basis, the collectability of accounts receivable is assessed based upon historical collection trends, current economic factors and the assessment of the collectability of specific accounts. We evaluate the collectability of specific accounts and determine when to grant credit to our customers using a combination of factors, including the age of the outstanding balances, evaluation of customers’ current and past financial condition, recent payment history, current economic environment, and discussions with appropriate Company personnel and with the customers directly. Accounts are written off when we determine the receivable will not be collected. | ||||||||||||
Inventories | Inventories are stated at the lower of cost (including materials, direct labor and applicable overhead) or market. Cost is determined by using the first-in, first-out method. The following table details the major components of inventory (in thousands): | ||||||||||||

Finished goods | 9,847 | 9,276 | |||||||||||
Total inventories | $ | 28,022 | $ | 26,266 | |||||||||
Accounts Payable | We reflect disbursements as trade accounts payable until such time as payments are presented to our bank for payment. At December 31, 2014 and 2013, disbursements totaling approximately $613,000 and $443,000, respectively, had not been presented for payment to our bank. | ||||||||||||
Income Taxes | We account for income taxes utilizing Accounting Standards Codification (ASC) 740, Income Taxes , or ASC 740. ASC 740 requires the asset and liability method for the recording of deferred income taxes, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statement and the tax bases of assets and liabilities, as measured at current enacted tax rates. When appropriate, we evaluate the need for a valuation allowance to reduce deferred tax assets. | ||||||||||||
ASC 740 also requires the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attributes of income tax positions taken or expected to be taken on a tax return. Under ASC 740, the impact of an uncertain tax position taken or expected to be taken on an income tax return must be recognized in the financial statements at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized in the financial statements unless it is more-likely-than-not of being sustained. | |||||||||||||
Our uncertain tax positions are recorded as “Other non-current liabilities.” We classify interest expense on underpayments of income taxes and accrued penalties related to unrecognized tax benefits in the income tax provision. | |||||||||||||
Property Plant and Equipment | Property, plant and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. Additions and improvements are capitalized, including all material, labor and engineering costs to design, install or improve the asset. Expenditures for repairs and maintenance are charged to expense as incurred. The following table represents a summary of property, plant and equipment at original cost (in thousands): | ||||||||||||

Total property, plant and equipment | $ | 142,171 | $ | 130,504 | |||||||||
Depreciation expense of $8,454,000, $8,413,000 and $7,448,000 was recorded for the years ended December 31, 2014, 2013 and 2012, respectively. Depreciation expense is recorded in either cost of goods sold or operating expenses based on the associated assets’ usage. | |||||||||||||
Patents and Licenses | Costs for patents and licenses acquired are determined at acquisition date. Patents and licenses are amortized over the useful lives of the individual patents and licenses, which are from 7 to 20 years. Patents and licenses are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. | ||||||||||||
Goodwill | Goodwill represents the excess of cost over the fair value of tangible and identifiable intangible net assets acquired. Annual impairment testing for goodwill is done using a qualitative assessment on goodwill impairment to determine whether it is necessary to perform the two-step goodwill impairment test. Goodwill is also reviewed whenever events or changes in circumstances indicate a change in value may have occurred. We have identified three reporting units where goodwill was recorded for purposes of testing goodwill impairment annually: (1) Atrion Medical Products, Inc., (2) Halkey-Roberts Corporation and (3) Quest Medical, Inc. The total carrying amount of goodwill in each of the years ended December 31, 2014, 2013 and 2012 was $9,730,000. Our evaluation of goodwill during each year resulted in no impairment losses. | ||||||||||||

Total accrued liabilities | $ | 4,950 | $ | 4,423 | |||||||||
Revenues | We recognize revenue when our products are shipped to our customers, provided an arrangement exists, the fee is fixed and determinable and collectability is reasonably assured. All risks and rewards of ownership pass to the customer upon shipment. Net sales represent gross sales invoiced to customers, less certain related charges, including discounts, returns and other allowances. Revenues are recorded exclusive of sales and similar taxes. Returns, discounts and other allowances have been insignificant historically. | ||||||||||||
Shipping and Handling Policy | Shipping and handling fees charged to customers are reported as revenue and all shipping and handling costs incurred related to products sold are reported as cost of goods sold. | ||||||||||||
Research and Development Costs | Research and development costs relating to the development of new products and improvements of existing products are expensed as incurred. | ||||||||||||
Stock-Based Compensation | We have stock-based compensation plans covering certain of our officers, directors and key employees. As explained in detail in Note 8, we account for stock-based compensation utilizing the fair value recognition provisions of ASC 718, Compensation-Stock Compensation, or ASC 718. | ||||||||||||
New Accounting Pronouncements | From time to time, new accounting pronouncements applicable to us are issued by the Financial Accounting Standards Board, or FASB, or other standards setting bodies, which we will adopt as of the specified effective date. Unless otherwise discussed, we believe the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial statements upon adoption. | ||||||||||||
Fair Value Measurements | Accounting standards use a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. These tiers are: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists therefore requiring an entity to develop its own assumptions. | ||||||||||||
As of December 31, 2014 and 2013, we held certain investments in corporate and government debt securities as well as certain equity securities. These investments are all considered Level 2 assets and the fair value of our investments were estimated using recently executed transactions and market price quotations (see Note 2). | |||||||||||||
The carrying values of our other financial instruments including cash and cash equivalents, money market accounts, accounts receivable, accounts payable, accrued liabilities, and accrued income and other taxes approximated fair value due to their liquid and short-term nature. | |||||||||||||
Concentration of Credit Risk | Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. | ||||||||||||
Our cash and cash equivalents are held in accounts with financial institutions that we believe are creditworthy. Certain of these amounts at times may exceed federally-insured limits. At December 31, 2014, approximately 91% of our cash and cash equivalents were uninsured. We have not experienced any credit losses in such accounts and do not believe we are exposed to any significant credit risk on these funds. | |||||||||||||
We have investments in United States government agency securities and corporate bonds. As a result, we are exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer and otherwise. Approximately 24% of our aggregate fixed-income investments are below investment grade. These securities have a higher degree of credit or default risk and a greater exposure to credit risk and may be less liquid in times of economic weakness or market disruptions. | |||||||||||||
For accounts receivable, we perform ongoing credit evaluations of our customers’ financial condition and generally do not require collateral. We maintain reserves for possible credit losses. As of December 31, 2014 and 2013, we had allowances for doubtful accounts of approximately $22,000 and $86,000, respectively. The carrying amount of the receivables approximates their fair value. Our customer that generates our largest revenues accounted for 6.5%, 8.2% and 16.3% of accounts receivable as of December 31, 2014, 2013 and 2012, respectively. No other customer exceeded 10% of our accounts receivable as of December 31, 2014, 2013 or 2012. | |||||||||||||
